我正在尝试下载一个网站及其子网站和子网站(如果存在)等的所有内容(文档,列表,文件夹),我可以为单个网站做到这一点,但它不适用于其子网站,代码如下,

   private void downloadList(SPObjectData objectData)
    {
        using (SPWeb currentWeb = objectData.Web)
        {
            foreach (SPList list in currentWeb.Lists)
            {
                    foreach (SPFolder oFolder in list.Folders)
                    {
                        if (oFolder != null)
                        {
                            foreach (SPFile file in oFolder.files)
                            {
                                if (CreateDirectoryStructure(tbDirectory.Text, file.Url))
                                {
                                    var filepath = System.IO.Path.Combine(tbDirectory.Text, file.Url);
                                    byte[] binFile = file.OpenBinary();
                                    System.IO.FileStream fstream = System.IO.File.Create(filepath);
                                    fstream.Write(binFile, 0, binFile.Length);
                                    fstream.Close();
                                }
                            }
                        }
                }
            }
        }
    }

这是因为您希望对子网站进行递归处理

foreach(SPWeb oWeb in currentWeb.Webs){
downloadList(oWeb); //use same logic you used above to get all the stuff from the sub web
}

那么,你的递归方法应该是这样的:

//notice I overloaded
private void downloadList(SPWeb oWeb){
//get subwebs of subwebs
foreach(SPWeb oWeb in currentWeb.Webs){
   downloadList(oWeb); 
}
foreach (SPList list in oWeb.Lists)
            {
                    foreach (SPFolder oFolder in list.Folders)
                    {
                        if (oFolder != null)
                        {
                            foreach (SPFile file in oFolder.files)
                            {
                                if (CreateDirectoryStructure(tbDirectory.Text, file.Url))
                                {
                                    var filepath = System.IO.Path.Combine(tbDirectory.Text, file.Url);
                                    byte[] binFile = file.OpenBinary();
                                    System.IO.FileStream fstream = System.IO.File.Create(filepath);
                                    fstream.Write(binFile, 0, binFile.Length);
                                    fstream.Close();
                                }
                            }
                        }
                }
            }
        }
